The sewer system for collecting municipal wastewater, wastewater treatment and the discharge of wastewater treatment plants (WWTP) contribute to the emissions of greenhouse gases (GHG) in direct emissions. The potential of global warming of GHGs emission were represented by carbon dioxide (CO2 ) and expressed as equivalent carbon dioxide (CO2-eq). The GHG emissions in cities of developing countries, such as Indonesia, were predicted increase in the future. However, developing countries still have problems in quantifying of GHG emission. The aim of this paper is estimating GHG emissions by calculating methane (CH4) and nitrous oxide (N2O) from domestics wastewater treatment and discharge in East Java Province, Indonesia. The result show that from domestic wastewater in East Java Province contribute GHG emissions 3,417,655 ton CO2-eq in 2017. This emission will increase 6.08% up to 3,625,692 ton CO2-eq in 2026. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2021.
